It seems that due to a change in the default configuration:
https://github.com/kyverno/kyverno/commit/eb72b04d2c130fabd39bdd0eec0ea36fd8a08c70
The metric kyverno_policy_rule_info_total is being exported without the namespace, and that causes it to not report per-tool metrics. Given that it's what we use for alerts and graphs (https://grafana-rw.wmcloud.org/d/kyverno/kyverno), we should either fix it or stop using that metric.
The alert Toolforge Kyverno has low amount of policy resources.
